As far as i know they are used for collision detection, so that u dont have 2 callculate precise collision if for example the character is nowhere near the wall, so only calculating whithin the first big section that u were in and following it down untill u have a precise calculation, rather than checking with every object every time. I dont know if this makes sence. Someone will say something better, but 2 be fair Ive only had 4 hours sleep... Chris
